BUILDING-BRICK.

SPECIFICATION forming part of Letters Patent No. 468,990, dated February 16, 1892.

Application filed December 29. 1890. Serial No. 376,173. (No mo'lel.)

To all whom/t may concern..-

1e it known that, I, JOSEPH RAPP, of New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented certain new and.

eut tiles embodying my invention, but modi-` fied somewhat, according to circumstances.

A represents a tile, as shown in Fig. l, having a fiat face A and having an ornamental face A2. This tile is adapted, for instance, for facing walls, although a Wall of moderate thickness could be constructed of a single tier of such tiles laid, of course, the one layer upon Ithe other, so that the tiles will break joints endwise. provided, as shown, with a series of `grooves ZJ with undercut walls for plastering thereon, in which case the ornamental faces A2 would likely form the outer face of the wall and the inner face of the wall would be plastered. The molded or ornamented faces have depending lips or flanges c, adapted to conceal the joints next below, so as to protect the joints rfrom the weather.

In Fig. 2 the one face of the tile is The tiles have two chambers a, divided by an internal vertical partition a', connecting the top and bottom walls to give these walls greater strength as against crushing. The

tiles are provided, top and bottom, respect- 4o the bottom-#whereby are avoided sharp ann gles or corners that are objectionable because they tend to weaken the tile and are liable to produce cracks in the tile in tiring.

Vhat I claim is- A hollow tile having a grooveron one face and tongue on the opposite face and a partiv tion extending between the tongu e and groove,

substantially as set forth.

`In testimony whereof I sign this specification, in the presence of two Witnesses, this 15th day of December, 1890.

JOSEPH RAPP.
